<p>Disclosed are a capacitive touch control device (100) and a method thereof. A top face of a substrate (1) is provided with first and second electrode groups (G1; G2), which each include a plurality of strip-like electrodes (21, ..., 25; 31, ..., 35) spaced from each other by a preset distance. The electrodes (21, ..., 25; 31, ..., 35) of the first and second electrode groups (G1; G2) are respectively connected by first and second group scanning lines (41; 42) to a scanning circuit (4). When the first group scanning lines (41) drive the electrodes (21, ..., 25) of the first electrode group (G1), the second group scanning lines (42) carry out scanning operation on the electrodes (31, ..., 35) of the second electrode group (G2), and when the second group scanning lines (42) drive the electrodes (31, ..., 35) of the second electrode group (G2), the first group scanning lines (41) carry out scanning operation on the electrodes (21, ..., 25) of the first electrode group (G1). And, a touch location can thus be determined by using a microprocessor (5).</p> |
